About Converting Microliters to Petaliters
Microliter and Petaliter appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Specifically: Microliter is 0.000001 liter units, and petaliter is 1000000000000000 liter units.
Formula
petaliters = microliters × 1e-21
This factor comes from each unit's defined relationship to the category's base unit: 1 microliter equals 1e-9 base units, and 1 petaliter equals 1e+12 base units, so dividing one by the other gives the direct microliter-to-petaliter factor of 1e-21.
Simple example
1 uL × 1e-21 = 1e-21 PL
1 microliter = 1e-21 petaliters.
Real-world example
10 uL × 1e-21 = 1e-20 PL
10 microliters = 1e-20 petaliters.
